free-code Claude CLI Skill by ara.so — Daily 2026 Skills collection. free-code is a buildable fork of Anthropic's Claude Code CLI — a terminal-native AI coding agent. It removes all telemetry and phone-home callbacks, strips Anthropic's injected system-prompt guardrails, and unlocks 54 experimental feature flags that are disabled in the public npm release. It supports five model providers: Anthropic, OpenAI Codex, AWS Bedrock, Google Vertex AI, and Anthropic Foundry. Installation One-liner (recommended) curl -fsSL https://raw.githubusercontent.com/paoloanzn/free-code/main/install.sh | bash This installs Bun if needed, clones the repo, builds with experimental features, and symlinks free-code on your PATH . Manual build

Requires Bun >= 1.3.11

curl -fsSL https://bun.sh/install | bash git clone https://github.com/paoloanzn/free-code.git cd free-code bun run build ./cli Key CLI Commands

free-code: command not found after install The install script symlinks to your PATH. If it's missing: cd free-code ln -sf " $( pwd ) /cli" /usr/local/bin/free-code Build fails on experimental flags Some of the 88 flags don't compile cleanly. Use build:dev:full which only enables the 54 working flags. For broken flags, check FEATURES.md for reconstruction notes:

Safe full-unlock build (54 working flags only)

bun run build:dev:full Authentication errors with Bedrock Verify your AWS credential chain is working independently: aws sts get-caller-identity

If this fails, fix AWS credentials before setting CLAUDE_CODE_USE_BEDROCK=1

Vertex AI auth errors gcloud auth application-default login gcloud auth application-default print-access-token

verify it works
